Strap for Classique Minute Repeater 7637 Rose Gold / Silver

The Breguet Classique Complications 7637BR/12/9ZU is fitted with an 18 mm strap attachment. To verify this on your own watch, measure the internal distance between the case lugs at the strap attachment point using a digital caliper or millimeter ruler.

For this rose gold reference with a guilloché dial, the most suitable strap is Porosus alligator in bordeaux or cognac brown: the natural grain complements the hand-worked texture of the dial. Alternatively, box-calf leather develops an elegant patina over time that perfectly suits the watch's classical character.

Strap replacement requires a proper springbar tool to remove the attachment bars from the 18 mm lugs. We recommend entrusting this task to an experienced watchmaker or specialized atelier such as Casati Milano to avoid scratches on the rose gold case and ensure correct positioning of the new strap.

Yes. Any strap with 18 mm attachment is technically compatible. Milano Straps offers handcrafted straps in alligator, calf leather, and other materials selected specifically for high-end watches with 18 mm lugs, featuring finishes and stitching suitable for the 7637BR/12/9ZU.

A quality leather strap—alligator or box-calf—on a wristwatch typically lasts between 18 months to 3 years, depending on frequency of use, exposure to perspiration, and daily care. Avoiding prolonged contact with water and creams, and storing the watch without a strap under tension significantly extends its lifespan. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
